I’m using APSync 4.19.66-v7+ image on my Pi to communicate with PX4 Autopilot. In following this guide provided by Ardupilot, it describes a configuration file for a service ‘mavlink-router’ that I don’t see present on my Pi’s filesystem (~/start_mavlink-router/mavlink-router.conf). I’d like to face MavProxy towards the AP it has made at the default address 10.0.1.128, and also be able to connect with QGroundControl. I’m able to SSH into Pi once connected with Desktop, and connect with USB. How do I proceed?
